Duke University botanists have named 19 species of a new genus of fern after Lady Gaga, according to the New York Times. The fern has "somewhat fluid definitions of gender" and is found in Arizona, Texas and Mexico, as well as Central and South America. A grad student also found the sequence GAGA in the DNA base pairs of the fern. "We wanted to name this genus for Lady Gaga because of her fervent defense of equality and individual expression," Kathleen Pryer, director of Duke's herbarium and professor of biology, told the Times. "And as we started to consider it, the ferns themselves gave us more reasons why it was a good choice."
